SNOW-PLOW.

SPECIFICATON forming part of Letters Patent No. 638,414, dated December5, 1899.

Application filed April 19,1899. Serial No. 713,531. (No model.)

T0 all whom it may concern:

Be it known that I, GEORGE R. HUFF, a citizen of the UnitedStates,vresiding at St. Croix Falls, in the county of Polk and State ofWisconsin, have invented an Improvement in Snow-Flows, of which thefollowing is a specification.

My invention relates to improvements in snow-plows, and moreparticularly to that class adapted to be attached to locomotives andthrow snow to either side of the track.

To this end my invention consists of a scoop having one or more inclinedchutes.

The plow is mounted upon a truck and propelled by a locomotive, thusforcing the snow through the chutes and throwing it to either side ofthe track.

In the accompanying drawings, forming part of this specification, Figurel is a side elevation of my improved snow-plow shown connected to alocomotive. Fig. 2 is a plan View of Fig. 1, showing the auxiliary plowremoved. Fig. 3 is a plan view of the plow. Figs. 4 and 5 are detailviews of one of the knives, and Fig. 6 is a side elevation of analternate construction of plow.

In the drawings, let A represent my improved snow-plow, and B and'Cthose portions of the plow which for convenience throughout thisspecification are called, respectively, the scoop and chute The chute Cextends rearwardly and inclines upwardly from the scoop. The plow ismounted upon the truck D, which connects to the locomotive by means ofthe draw-bar 2. The lower frame 3 of the scoop is closely adjacent tothe railroad-track 4 and is preferably wedge-shaped, as shown in Fig. 2.The upper frame 5 is substantially parallel and positioned to the rearof the lower frame. The scoop is provided with side walls 9. Thedistributingknives 6, which are formed with the cutting edges 7, arefastened across the mouth G of the scoop to the edges of the lower andupper frames by means of bolts 8. These knives are adapted to cut anddistribute the snow, so as to prevent the scoop and chutes from choking.The chute O is bifurcated, with its members 10 and 1l on either side ofthe smoke-stack 12 of the locomotive E. The outer ends of the chutes arepreferably curved, so as to throw the snow abruptly to either side ofthe track. While the members of the chute are substantially square incross-section, it is obvious that their construction may be of anysuitable shape. Each member of the chute O is composed of walls 13 andthe outer ends are formed Vwith openings 14. To support the chute isprovided the brace 15, which is fastened by means of bolts 16 andprovided with the bearing-plate 17, which is movably supported by theframe 18 of the locomotive.

WVhen the snow is of greater depth than can be removed by the scoop, Iprovide an auxiliary snow-plow F, which is formed with the cutting edge19'and the mold-boards 20, which are suitably curved so as to throw thesnow abruptly to either side of the track. The auxiliary plow isfastened to the main plow by means of bolts 21. The outer walls or sides22 of the main plow are provided with openings 23 for additionallyplowing the snow, having the inclined knives 24 for distributing orcutting purposes.

The knives of the plow are shown inclined; but it is obvious the knivesmay be horizontal, as shown in Fig. 5. Also when the friction of thesnow causes choking aprons 25 and 26 may be provided on the outer andlower faces 27 and 28 of each member of the chute O. These aprons,constructed of canvas or other suitable material, are endless in formand pass over the rolls 29, which are journaled on the chutes.

It is obvious an operative snow-plow may be constructed with a singlechute or for use by hand, in which case the truck is discarded andahandle fastened in its place for propelling the plow. The lower plate insuch case bears upon the ground.

Having described my invention, what I claim as new, and desire to secureby Letters Patent, is-

1. A snow-plow, consisting of a scoop having a mouth and Wedge-shapedframes; cutting or distributing knives mounted upon said frames acrosssaid mouth; a bifurcated chute leading from said scoop; in combinationwith the truck and the means for supporting the plow and connecting thetruck to the locomotive as shown, and for the purposes specified.

2. A snow-plow, consisting in combination with the locomotive of ascoophavinga wedge- IOC) mouth; cutting or distributing knives inclinedacross said mouth; an upwardly and outwardly inclined bifurcated chuteleading from said scoop; the truck for carrying said plow and the meansfor supporting said plow and connecting said truck to the locomotive asshown7 and for the purposes specified.

3. A snow-plow, consisting in combination with the locomotive of ascoopBhavingasuitable opening; cutting or distributing knives 6 inclinedacross said opening; a bifurcated chute C inclined from said scoop; anauxill l l l iary plow F, mounted upon said scoop and chute; the truckfor carrying said plow, and the means for supporting said plow andconnectingsaid'truck to the locomotive as shown, and for the purposesspecified.

In testimony whereof I affix my signature, in presence of two Witnesses,this 25th day of March, 1899.

GEORGE R. HUFF.
